Abstract [en]

Timing permeates everyday activities such as walking, dancing and music, yet the effect of short-term practicein this ubiquitous activity is largely unknown. In two training experiments involving sessions spreadacross several days, we examined short-term practice effects on timing variability in a sequential intervalproduction task. In Experiment 1, we varied the mode of response (e.g., drumstick and finger tapping) andthe level of sensory feedback. In Experiment 2 we varied the interval in 18 levels ranging from 500 ms to1624 ms. Both experiments showed a substantial decrease in variability within the first hour of practice,but little thereafter. This effect was similar across mode of response, amount of feedback, and interval duration,and was manifested as a reduction in both local variability (between neighboring intervals) and drift(fluctuation across multiple intervals). The results suggest mainly effects on motor implementation ratherthan on cognitive timing processes, and have methodological implications for timing studies that have notcontrolled for practice.
